Successful completion of Human rating of CE20 Cryogenic engine for the Gaganyaan Programme

ISRO has accomplished a major milestone in the human rating of its CE20 cryogenic engine that powers the cryogenic stage of the human-rated LVM3 launch vehicle for Gaganyaan missions, with the completion of the final round of ground qualification tests on February 13, 2024. The final test was the seventh of a series of vacuum ignition tests carried out at the High Altitude Test Facility at ISRO Propulsion Complex, Mahendragiri, to simulate the flight conditions.

The ground qualification tests for the human rating of the CE20 engine involved life demonstration tests, endurance tests, and performance assessment under nominal operating conditions as well as off-nominal conditions w.r.t thrust, mixture ratio, and propellant tank pressure. All the ground qualification tests of the CE20 engine for the Gaganyaan programme have been successfully completed.

In order to qualify the CE20 engine for human rating standards, four engines have undergone 39 hot firing tests under different operating conditions for a cumulative duration of 8810 seconds against the minimum human rating qualification standard requirement of 6350 seconds.

ISRO has also successfully completed the acceptance tests of the flight engine identified for the first unmanned Gaganyaan (G1) mission tentatively scheduled for Q2 of 2024. This engine will power the upper stage of the human-rated LVM3 vehicle and has a thrust capability of 19 to 22 tonnes with a specific impulse of 442.5 seconds.

Gaganyaan
November 23, 2022

The primary mandate of HSFC is to spearhead ISRO's Gaganyaan programme through co-ordinated efforts and focus all the activities that are carried out in other ISRO centres, research labs in India, Indian academia and Industries towards accomplishing the mission. HSFC, as the lead Centre for Human space flight activities conforms to high standards of reliability and human safety in undertaking R&D activities in new technology areas, such as life support systems, Human Factors Engineering, Bioastronautics, Crew training and Human rating & certification. These areas would constitute important components for future sustained human space flight activities like rendezvous and docking, space station building and interplanetary collaborative manned missions to Moon/Mars and near-earth asteroids.

Gaganyaan

Gaganyaan project envisages demonstration of human spaceflight capability by launching crew of 3 members to an orbit of 400 km for a 3 days mission and bring them back safely to earth, by landing in Indian sea waters.

The project is accomplished through an optimal strategy by considering inhouse expertise, experience of Indian industry, intellectual capabilities of Indian academia & research institutions along with cutting edge technologies available with international agencies. The pre-requisites for Gaganyaan mission include development of many critical technologies including human rated launch vehicle for carrying crew safely to space, Life Support System to provide an earth like environment to crew in space, crew emergency escape provision and evolving crew management aspects for training, recovery and rehabilitation of crew.

Various precursor missions are planned for demonstrating the Technology Preparedness Levels before carrying out the actual Human Space Flight mission. These demonstrator missions include Integrated Air Drop Test (IADT), Pad Abort Test (PAT) and Test Vehicle (TV) flights. Safety and reliability of all systems will be proven in unmanned missions preceding manned mission.

Human rated LVM3 - HLVM3

LVM3 rocket - The well proven and reliable heavy lift launcher of ISRO, is identified as the launch vehicle for Gaganyaan mission. It consists of solid stage, liquid stage and cryogenic stage. All systems in LVM3 launch vehicle are re-configured to meet human rating requirements and christened Human Rated LVM3. HLVM3 will be capable of launching the Orbital Module to an intended Low Earth Orbit of 400 km.

HLVM3 consists of Crew Escape System (CES) powered by a set of quick acting, high burn rate solid motors which ensures that Crew Module along with crew is taken to a safe distance in case of any emergency either at launch pad or during ascent phase.

Orbital Module

Orbital Module (OM) that will be Orbiting Earth comprises of Crew Module (CM) and Service Module (SM). OM is equipped with state-of-the-art avionics systems with adequate redundancy considering human safety.

CM is the habitable space with Earth like environment in space for the crew. It is of double walled construction consisting of pressurized metallic Inner Structure and unpressurised External Structure with Thermal Protection System (TPS). It houses the crew interfaces, human centric products, life support system, avionics and deceleration systems. It is also designed for re-entry to ensure safety of the crew during descent till touchdown.
SM will be used for providing necessary support to CM while in orbit. It is an unpressurized structure containing thermal system, propulsion system, power systems, avionics systems and deployment mechanisms.

New technologies being developed for Gaganyaan

Human safety is of paramount importance in Gaganyaan mission. In order to ensure the same, various new technologies comprising of Engineering systems and Human centric systems are being developed and realised.

Crew training for Gaganyaan

Astronaut Training Facility established in Bengaluru caters to Classroom training, Physical Fitness training, Simulator training and Flight suit training. Training modules cover academic courses, Gaganyaan Flight Systems, Micro-gravity familiarization through Parabolic Flights, Aero-medical training, Recovery & Survival training, mastering of Flight Procedures and training on Crew Training Simulators. Aero medical training, Periodical flying practice and Yoga are also included as part of the training.

From TitaniumSV5:
Somanath sir in the press conf:

1. TV-D2 test will be in next 2 months.
2. Chandrayaan-4 LSR in design phase.
3. INSAT-3D to be repurposed for 'an experiment'.
4. NGLV study phase done, design work has started, next step is govt funding approval.

Quoting tweet for record.

#BREAKING

-Unconfirmed news that Gp Capt Prashanth Balakrishnan Nair, an #IndianAirForce Su-30 pilot would lead the #Gaganyaan as Commander -We must wait for #PMModi's #Kerala visit tomorrow, where he is likely to disclose this information to the nation

 

[TopWatcher]

How does SLIM revive after moon night, are they using RHU ?

 

[Jimih]

So he might be the India's real-life Captain Vyom.

One more name can be in the crew list and that is of Wg Cmdr Nikhil Rath.


All 4 names will be revealed tomorrow

 

[TopWatcher]

What somnaath sir trying to say??

 

[notaname]

What somnaath sir trying to say??

He is saying our lander didn't tip over like other landers (Like JAXA or Intuitive) and was intact.

And were able to get the pictures as well.
